Last year's series exploring the lives of the trawlermen fishing the North Sea was epic and well-received; this takes the best bits and adds new footage, tying up loose ends and expanding on some relationships to make a complete version: "FISH: The Movie". It's a dramatic portrait of the men, their families, the storm-thrashed derring-do of the catch and the pressure to turn profit. Only finding out that farmers have to battle angry potato monsters and steal chips from their nests could make the plain old fish supper more exciting.

Supernanny

8pm, Channel 4

After years of trying for a baby, Ann and Steve Gormley-Brickley were overjoyed when they were blessed with twins after a course of IVF. A year after their birth, discovering they were pregnant with more twins, the joy was tinged with a hint of panic. Supernanny marches in to take the family in hand - it's one of those weeks when you admire her ability to instil a gentle sense of control and confidence back into the parents, rather than her restraint at not running out the door screaming: "I give up! Stick it back up there and start again!"

Heroes

9pm, BBC2

Mohinder begins to have visions of the past, Hiro meets a girl and Isaac is under pressure to paint the future on demand. Later, on BBC3, it seems that we've hit the crisis that the entire half of this series has been building up to. But then again, it's hard to be sure - have we?! Those sucked in to this ridiculous and addictive series will experience a familiar panic as the credits roll - as the BBC announces they've got lovely interactive features online, and the fans shout: "Screw your interactivity - I need the next episode and I need it NOW."

Hell's Kitchen

9pm, ITV1

Three days into Hell's Kitchen 3, and the celebrities are getting into the swing of things. Well, not really. Always fun to see "proper" celebrities griping about the presence of "reality" celebrities, though, while we sit around and try to remember when we last saw those proper celebrities in something other than reality TV. Marco Pierre White, though less wrinkly than Gordon, is similarly tough and efficient, while his two kitchens battle to feed a room full of hungry C-listers.
